To ALL wHoM Ir 'MAY coNcEnN: y t l Be it known that I, HERMAN SPIuO, ofKnoxville, in the county of Knox, and State of Tennessee', have inventeda new and useful Improvement'. in Brick and Mortar-Elevators.; and I dohereby dechire 'that the folloning'is a full, clear, and exactdescription t usethe same, reference being hsd'to the accompanyingdrawings, forming part -of this specication, in ulrich- Figure 1 is asectional elevation of my invention, the section being taken through theline a: a: of fig. 2.

Figure 2 is a front elevation of the same. l Similar letters ofreference indicate corresponding parts. The object of this inventionisto accomplish the raising. of, brick and mortar for btiildingppurposes,and to le to rthe builders upon the scaffolding.

It consists of the mechanism set forth in the following. In theaccompanying drawings, B B arcupright srisingfrom the baset`rame G E H.D is a cross-piece, ng an o ctagonal forn1 ,'or other equivalent means,for 'preventing the 'endl'esshelt ci' buckets from slipping thereon. I

'lhe'belt is composed of short boards, g g g, aixed to hinge-plates,fff,ic., the said plates being connected by pintle-rods, h h h, 85e.,passing through the eyes of the said plates. These rods are capable ofbeing witbsto be lengthened, as the build drawn laterally, for thepurpose of interpolating other boards, when the belt 'i ing rises. A

The nprights B are formed of twoor more beams of i'rood, having theirends cut to form a scarf orlapped joint, as shown at Q, irhereby theuprighl't's may be lengthened to correspond with the increased height ofthe building, as its erection progresses. I I l The boxes I are aixed tothe boards of the belt at suitable interv the bricks to be elevated.

Thdmortar is borne up in triangular boxes J, which are hooked on tohooks a l: aliixed to the belt-boards.

Each pair 'of hooks, a and b,'are turned reversely from each other, asshown, the hooks b being for carrying up the mortar-boxes, and the hooksa for bringing them donn; the boxes being takenfrom the hooks b by anattendanton the scali`oldand emptied into a box upon the scaffold, andhooked on to the hooks a, to be sent down for reiilling. They nre againremoved hy an attendant .at the basent" the machine and filled, and hungupon the hooks b'as thelatter are turned upward to ascend.

The briclbhoxesare only large enough to contain one brckkand are {illedby au attendant as they pass under the lower .drum and commence toascend. As these boxes become inverted in passing 'over the upper thebrick falls ont, and is caught by an attendant standing un the scalolengages with a pinion, l, the shaft olf nhichbears a handals, and arefor the purposeof containing drum,

A cog-wheel, m, on the shaft k oi' thc loner drum,

cranlt', R, by means oi' which the machine is operated.

The shal'tj of the u'pper drum has its bearings in the links d dloosely. The uprghts and the cross-part of the said links rest on theshoulders P, nhich latter may be cut in thc uprights or formed of aplate of metal, as shown, and :ailixed to the uprights. These shouldersthus sustain thencigh't of the upper drum, and the belt of boxes andtheir contents.

The uprights are originally made of sniiieient height for buildings ofordinary or medium height, and es the worlt progresses, additionalboardsand bucketsare interpolated in the belt, and theupper dru'm raisedcorrespondingly by ropes or cords K, which pass over the pulleys L L,suspended vfrom a cross-bar or rod, M, which latter is attached to theuprights by loose links N, the latter being sustained by the bolts O O,r other equivalent devices. l Y

The ropes K K terminate in hooks e, which are sot into the eyes, formingpart of -the links d d, as shown. h, S, which operation raises the upperdrum and straightens the The ropes are then moved in' a windlsss'or winelengthened belt. it are rollers, ou the-shaftj, for preventing thelinlts from cramping against the uprights.

hereof, which will enable others skilled in theni-tV to make and.

llxvhngthus descibed my-finventlon, I claim os new, and desire toseoux'e Letters Patent- "IL'vThe drums A A, belt g g g, fff, boxes I andJ, and hooks a b,all substantially ssshown.andidewrbeth f y incombination with the uprights-B, all as ond for the purpose set. forth.
